PETER B. CRANE, or LONG LAKE, MINNESOTA.

DEEP-TILLING MAOI-ILIIVE.

Application filed September 17, 1915. Serial No. 51,180.

To all whom it may concern:

Be it known that I, PETER B, CRANE, citizen of the United States, resident of Long Lake, county of I-Iennepin, State of Minnesota, have invented gcertain new and useful Improvements in Deep-Tillingi Machines, of which the following is a specification.

My invention relates'to a disk tilling machine wherein a single disk is employedjfor turning a furrow, one carrying wheel traveling on the landside of the machine and another wheel traveling in the furrow previously cut by the disk. y y l A disk plow as generally constructed will plow adeep furrow in soft soil where there is but little resistance and a shallow furrow in hard-resisting soil. This obviously does not produce a desirable result, as. there lack of uniformity in the depth of the seeding bed and uneven growth of. the plants. The primary object of my invention is to provide a disk plow which will reach a greater depth and will maintain a uniform depth or out and width of furrow regardless of soil conditions and resistance to the disk.

A further object is to provide means for resisting or overcoming the natural tendency of the plow disk to work to the landward side as the machine is moved along.

A further object is to provide a construe.

tion which will adapt the for work on a side hill. l The invention consists generally. in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification, H

forward and rear portions of the frame tothem in their proper plow disk and formsa direct connection between the disk and the motive power.

A casting 7 is mounted upon the brace 5 and is rigidly secured thereto by bolts 8 or other suitable means. A carrying wheel 9 is mounted on the lower end of a spindle 10* i that is ournalcd 1n bear ngs 11 and has an arm 12 at its upper end projecting inwardly over the forward portion of the frame 2 for convenience in rocking thespindle 10 and changingthe angle of the wheel 9 with respect to. the wall of the furrow; The spina dle lQis free to slide vertically in its bearing; and is raised and lowered by suitable means, preferably a lever 18. pivoted on a frame 145 that ismounted on the bearing 11 and con nectedbya link 15 with the lower portion of the spindle. The leveris movable over a rack 165 On the oppositeside of the frame isa wheel 18 journaledon an arm 19 that is pivoted at 20 on the rearportion of the frame. This arm19 is rocked in a vertical plane to raise or lower the wheel 18 by means of a link 21connectinp; said arm with an operating lever22 that is movable over a toothed rack 23. a By the adjustment of these levers the position of the supporting Wheels canbe changed as desired in the operation The casting 7 has a box 2% formed thereon wlth a bearlng 25 for the stud 26 ofa disk "27. Thisdisk stands at an angle tothe' di- "rection of moveinentlof the machine and is concave-convex in form, wlth ts concave face toward the front oflthc machine. The

in machines of t A." re hearing at" the e orefer toirovide a socket 28 to receive the l l depending end 29 of an arm 30, said end being provided with a cellar 31 having aset screw 32 for locking the collar on the end of the arm. 'When' this set screw is loosened. the arm may be adjusted vertically 'to raise or lower the rear carryingwvheel 33 in regulating the depth of cut ofthedisk.

The socket 28 into which the end o f'the arm 30 is inserted prevents the disk from sagging oftto the right when ,plowing on a side "hill. The angle ofthis socket forces the disk to work toward the left crap the hill and on extremely steep side hills a lock device is provided as will hereinafter ap pear. This manner of mounting the arm 30 in its so'cketalso 'operatesto raise the diskout'of the soil in inaking a haw'turn. This latter I regard asan'import'ant feature of the invention, as the h'awturn'is the one most frt-"Jquently "made "with a machine of this typea-nd by mounting the arm ingthe manner described 'the plow disk'will'beautomatically raised without the operation of any of the 'levers- In the rear lilfe socket "28 the 1 Casting is'p'rovided with a slot 34 iiitowhicha plate 35 is inserted. This plate has notches of varying depth in its longitudinal edges and is adapted to bear on' the 'rearwardly extending'portion of the arm 30, as'sh'o'wn plainly in Fig. 3. Asthere'shown, the ar'mis in contact with 'thestraigl'it edge oftli e plate and is held thereby inwardly toward the landside of the n'iaehine. 'Incase, however, the plate 35 is reversed, the arm may enter the notch 36 and thereuponbe free to swing for a limited distance outwardly. The other end of the plate is provided with notches 37 and 38 of varying depth and when the plate is inverted,0ne of thesenotehes will be brought into 'p'osition'to receive *the arm 30. The plate is provided with holes 39 to receive the pin 40 having'a -'hoeked end that is adapted to slip over the arm 30, as shown in Fig. 1, and hold the'dis'k up to'the work when the machine is in useon an eX- ti'emely steep side hill. The notches of varying depth in theplate 35 regulatethe lateral movement ofthe oasting'whereon the plow disk is supported and dete'rmine the width of the furrow. For instance, in Fig. 1 the plate -isshown wit-h its straight edge in contact with the arm and the disk is cutting a narrow furrow. Should this plate be reversed, the frame of the machine or the casting supporting the plow disk will be free to move inwardly toward the landr iide of "the machine and will thereby allow the disk to cut farther into the land and incr use the widthof the furrow. Furrows of varying width may be turned by the reversal or inversionef this plate to present notches of tained and the disk will, be prevented from working beyond the desired depth in soil of less resistance. I am thus able to provide for a uniform depth of furi'o'w in all conditions of soil. The machine is provided with the usual seat 44.

In the operation of the machine, the wheel 43 will prevent the disk fromdigginginto loose soil while the 'load *on the rear portion of the frame will hold the disk down in hard, tenacious soil to the same depth and thereby obtain a uniform depth of seed bed. The adjustment of the locking dcviee for the arm 30 will regulate the width of the furrow and thet'endency ofthe disk to dig into the soil on side hill, the lock device being utilized whenevernecessary to holdthe arm anddisk intlieirproperrelie tive position. r

In various ways the details of construction herein shown and described may he modified and 'stillbe'within the scope of my invention.
